A man has a very insecure tenure of a property which another can carry away with his eyes. A few months reduced me to the cruel necessity either of destroying my machine, or of giving it to the public. To destroy it, I could not think of; to give up that for which I had laboured so long, was cruel. I had no patent, nor the means of purchasing one. In preference to destroying, I gave it to the public.[On his inability to keep for himself a profitable income from his invention of the Spinning Mule.]

All frescoes are as high finished as miniatures or enamels, and they are known to be unchangeable; but oil, being a body itself, will drink or absorb very little colour, and changing yellow, and at length brown, destroys every colour it is mixed with, especially every delicate colour. It turns every permanent white to a yellow and brown putty, and has compelled the use of that destroyer of colour, white lead, which, when its protecting oil is evaporated, will become lead again. This is an awful thing to say to oil painters ; they may call it madness, but it is true. All the genuine old little pictures, called cabinet pictures, are in fresco and not in oil. Oil was not used except by blundering ignorance till after Vandyke’s time ; but the art of fresco painting being lost, oil became a fetter to genius and a dungeon to art.

Bottom trawling is a ghastly process that brings untold damage to sea beds that support ocean life. It’s akin to using a bulldozer to catch a butterfly, destroying a whole ecosystem for the sake of a few pounds of protein. We wouldn’t do this on land, so why do it in the oceans?

But if any skillful minister of nature shall apply force to matter, and by design torture and vex it, in order to [effect] its annihilation, it, on the contrary being brought under this necessity, changes and transforms itself into a strange variety of shapes and appearances; for nothing but the power of the Creator can annihilate, or truly destroy it.

Creating a new theory is not like destroying an old barn and erecting a skyscraper in its place. It is rather like climbing a mountain, gaining new and wider views, discovering unexpected connections between our starting point and its rich environment. But the point from which we started out still exists and can be seen, although it appears smaller and forms a tiny part of our broad view gained by the mastery of the obstacles on our adventurous way up.

Debate is an art form. It is about the winning of arguments. It is not about the discovery of truth. There are certain rules and procedures to debate that really have nothing to do with establishing fact–which creationists have mastered. Some of those rules are: never say anything positive about your own position because it can be attacked, but chip away at what appear to be the weaknesses in your opponent’s position. They are good at that. I don’t think I could beat the creationists at debate. I can tie them. But in courtrooms they are terrible, because in courtrooms you cannot give speeches. In a courtroom you have to answer direct questions about the positive status of your belief. We destroyed them in Arkansas. On the second day of the two-week trial we had our victory party!

Evolution is either an innocent scientific description of how certain earthly things came about; or, if it is anything more than this, it is an attack upon thought itself. If evolution destroys anything, it does not destroy religion but rationalism.

For, the great enemy of knowledge is not error, but inertness. All that we want is discussion, and then we are sure to do well, no matter what our blunders may be. One error conflicts with another; each destroys its opponent, and truth is evolved.

Gifford Pinchot points out that in colonial and pioneer days the forest was a foe and an obstacle to the settler. It had to be cleared away... But [now] as a nation we have not yet come to have a proper respect for the forest and to regard it as an indispensable part of our resources—one which is easily destroyed but difficult to replace; one which confers great benefits while it endures, but whose disappearance is accompanied by a train of evil consequences not readily foreseen and positively irreparable.

Concluding remark, in 'A Country that has Used up its Trees', The Outlook (24 Mar 1906), 82, 700. The topic of the article is the extensive deforestation in China, its consequences, and that America must avoid such massive problems.

Gluttony is the source of all our infirmities, and the fountain of all our diseases. As a lamp is choked by a superabundance of oil, a fire extinguished by excess of fuel, so is the natural health of the body destroyed by intemperate diet.

However, the small probability of a similar encounter [of the earth with a comet], can become very great in adding up over a huge sequence of centuries. It is easy to picture to oneself the effects of this impact upon the Earth. The axis and the motion of rotation changed; the seas abandoning their old position to throw themselves toward the new equator; a large part of men and animals drowned in this universal deluge, or destroyed by the violent tremor imparted to the terrestrial globe.

I am patriot enough to take pains to bring this usefull invention [smallpox inoculation] into fashion in England, and I should not fail to write to some of our Doctors very particularly about it, if I knew anyone of 'em that I thought had Virtue enough to destroy such a considerable branch of Revenue for the good of Mankind, but that Distemper is too beneficial to them not to expose to all their Resentment the hardy wight that should undertake to put an end to it.

I never pick up an item without thinking of how I might improve it. I never perfected an invention that I did not think about in terms of the service it might give others. I want to save and advance human life, not destroy it. I am proud of the fact that I never invented weapons to kill. The dove is my emblem.

If one of these elements, heat, becomes predominant in any body whatsoever, it destroys and dissolves all the others with its violence. …Again if too much moisture enters the channels of a body, and thus introduces disproportion, the other elements, adulterated by the liquid, are impaired, and the virtues of the mixture dissolved. This defect, in turn, may arise from the cooling properties of moist winds and breezes blowing upon the body. In the same way, increase or diminution of the proportion of air or of the earthy which is natural to the body may enfeeble the other elements.

If this [human kind’s extinction] happens I venture to hope that we shall not have destroyed the rat, an animal of considerable enterprise which stands as good a chance as any … of evolving toward intelligence.

It does not matter what men say in words, so long as their activities are controlled by settled instincts. The words may ultimately destroy the instincts. But until this has occurred, words do not count.

It is sometimes helpful to differentiate between the God of Miracles and the God of Order. When scientists use the word God, they usually mean the God of Order. …The God of Miracles intervenes in our affairs, performs miracles, destroys wicked cities, smites enemy armies, drowns the Pharaoh's troops, and avenges the pure and noble. …This is not to say that miracles cannot happen, only that they are outside what is commonly called science.

Modern war, even from the consideration of physical welfare, is not creative. Soldiers and civilians alike are supposed to put on mental khaki. … War means the death of that fertile war which consists of the free, restless conflict of ideas. The war which matters is that of the scientist with nature; of the farmer with the tawny desert; of … philosopher against … mob stupidity. Such war is creative. … Inventions that further life and joy; freedom; new knowledge, whether Luther Burbank’s about the breeding of fruits or Einstein's about relativity; great cathedrals and Beethoven's music: these modern mechanical war can destroy but never produce. At its most inventive height, war creates the Maxim gun, the submarine, disseminable germs of disease, life-blasting gases. Spiritually and intellectually, modern war is not creative.

As quoted, without citation, in Peter T. Davis and ‎Craig R. McGuffin, Wireless Local Area Networks: Technology, Issues, and Strategies (1995), 159. Various sources since then have the quote with that wording. This shares the same sentiment - and may be an alternate translation - as Nobel’s quote given by Linus Pauling in his Nobel Acceptance Speech (see elsewhere on this page). Pauling in his speech said it was from a statement by Nobel in 1892, as reported by Bertha von Sutter. Webmaster has so far found no definitive print source for either version.

Nothing can so quickly blur and distort the facts as desire—the wish to use the facts for some purpose of your own—and nothing can so surely destroy the truth. As soon as the witness wants to prove something he is no longer impartial and his evidence is no longer to be trusted.

Now, it may be stretching an analogy to compare epidemics of cholera—caused by a known agent—with that epidemic of violent crime which is destroying our cities. It is unlikely that our social problems can be traced to a single, clearly defined cause in the sense that a bacterial disease is ‘caused’ by a microbe. But, I daresay, social science is about as advanced in the late twentieth century as bacteriological science was in the mid nineteenth century. Our forerunners knew something about cholera; they sensed that its spread was associated with misdirected sewage, filth, and the influx of alien poor into crowded, urban tenements. And we know something about street crime; nowhere has it been reported that a member of the New York Stock Exchange has robbed ... at the point of a gun. Indeed, I am naively confident that an enlightened social scientist of the next century will be able to point out that we had available to us at least some of the clues to the cause of urban crime.

Power corrupts the few, while weakness corrupts the many.… The resentment of the weak does not spring from any injustice done to them but from the sense of their inadequacy and impotence. They hate not wickedness but weakness. When it is in their power to do so, the weak destroy weakness wherever they see it.

Something will have gone out of us as a people if we ever let the remaining wilderness be destroyed; if we permit the last virgin for-ests to be turned into comic books and plastic cigarette cases; if we drive the few remaining members of the wild species into zoos or to extinction; if we pollute the last clean air and dirty the last clean streams and push our paved roads through the last of the silence, so that never again will Americans be free in their own country from the noise, the exhausts, the stinks of human and automotive waste.

Suppose that we are wise enough to learn and know—and yet not wise enough to control our learning and knowledge, so that we use it to destroy ourselves? Even if that is so, knowledge remains better than ignorance. It is better to know—even if the knowledge endures only for the moment that comes before destruction—than to gain eternal life at the price of a dull and swinish lack of comprehension of a universe that swirls unseen before us in all its wonder. That was the choice of Achilles, and it is mine, too.

The big blue area that dominates the view of earth from space was once our home and today represents 97 percent of the biosphere where life exists, providing the water we drink and the air we breathe. And we are destroying it.

The electrical engineer has an enormous advantage over other engineers; everything lends itself to exact calculation, and a completed machine or any of its parts may he submitted to the most searching electrical and magnetic tests, since these tests, unlike those applied by other engineers, do not destroy the body tested.

The investigator may be made to dwell in a garret, he may be forced to live on crusts and wear dilapidated clothes, he may be deprived of social recognition, but if he has time, he can steadfastly devote himself to research. Take away his free time and he is utterly destroyed as a contributor to knowledge.

Letter to all State Governors on a Uniform Soil Conservation Law (26 Feb 1937). This is seen in a number of sources incorrectly joined with Roosevelt’s quote about forests as the lungs of the earth (q.v.), but Webmaster has only been able to find primary sources for these as separate quotes.

The number of humble-bees in any district depends in a great degree on the number of field-mice, which destroy their combs and nests; and Mr. H. Newman, who has long attended to the habits of humble-bees, ... says “Near villages and small towns I have found the nests of humble-bees more numerous than elsewhere, which I attribute to the number of cats that destroy the mice.” Hence it is quite credible that the presence of a feline animal in large numbers in a district might determine, through the intervention first of mice and then of bees, the frequency of certain flowers in that district!

The reformer [of the body of law] who would seek to improve such a system in any material degree, mistakes his vocation. That task had better be left to time and experience. He will often find it impossible to know what to eradicate and what to spare, and in plucking up the tares, the wheat may sometimes be destroyed. “The pound of flesh” may be removed, indeed, but with it will come, gushing forth, the blood of life.

The science of medicine is a barbarous jargon and the effects of our medicine on the human system are in the highest degree uncertain, except indeed that they have already destroyed more lives than war, pestilence, and famine combined.

The stakes are immense, the task colossal, the time is short. But we may hope–we must hope–that man’s own creation, man’s own genius, will not destroy him. Scholars, indeed all men, must move forward in the faith of that philosopher who held that there is no problem the human reason can propound which the human reason cannot reason out.

The true beauty of nature is her amplitude; she exists neither for nor because of us, and possesses a staying power that all our nuclear arsenals cannot threaten (much as we can easily destroy our puny selves).

This is a moment to seize. The kaleidoscope has been shaken. The pieces are in flux. Soon they will settle again. Before they do, let us re-order this world around us. Today, humankind has the science and technology to destroy itself or to provide prosperity to all. Yet science can’t make that choice for us. Only the moral power of a world acting as a community can.

This, as you know, is my opinion, that as the body when it tyrannizes over the mind ruins and destroys all its soundness, so in the same way when the mind becomes the tyrant, and not merely the true lord, it wastes and destroys the soundness of the body first, and then their common bond of union … and sins against prudence and charity.

Thus the system of the world only oscillates around a mean state from which it never departs except by a very small quantity. By virtue of its constitution and the law of gravity, it enjoys a stability that can be destroyed only by foreign causes, and we are certain that their action is undetectable from the time of the most ancient observations until our own day. This stability in the system of the world, which assures its duration, is one of the most notable among all phenomena, in that it exhibits in the heavens the same intention to maintain order in the universe that nature has so admirably observed on earth for the sake of preserving individuals and perpetuating species.

Time will soon destroy the works of famous painters and sculptors, but the Indian arrowhead will balk his efforts and Eternity will have to come to his aid. They are not fossil bones, but, as it were, fossil thoughts, forever reminding me of the mind that shaped them… . Myriads of arrow-points lie sleeping in the skin of the revolving earth, while meteors revolve in space. The footprint, the mind-print of the oldest men.

We are the only species that can destroy the Earth or take care of it and nurture all that live on this very special planet. I’m urging you to look on these things. For whatever reason, this planet was built specifically for us. Working on this planet is an absolute moral code. … Let’s go out and do what we were put on Earth to do.

We must protect each other against the attacks of those self-appointed watchdogs of patriotism now abroad in the land who irresponsibly pin red labels on anyone whom they wish to destroy. ... [Academic professionals are the only person competant to differentiate between honest independents and the Communists.] This is our responsibility. It is not a pleasant task. But if it is left to outsiders, the distinction is not likely to be made and those independent critics of social institutions among us who are one of the glories of a true university could be silenced.

Whatever answers faith gives.. .such answers always give an infinite meaning to the finite existence of man; a meaning that is not destroyed by suffering, deprivation or death. This means only in faith can we find the meaning and possibility of life.

While religion prescribes brotherly love in the relations among the individuals and groups, the actual spectacle more resembles a battlefield than an orchestra. Everywhere, in economic as well as in political life, the guiding principle is one of ruthless striving for success at the expense of one’s fellow men. This competitive spirit prevails even in school and, destroying all feelings of human fraternity and cooperation, conceives of achievement not as derived from the love for productive and thoughtful work, but as springing from personal ambition and fear of rejection.

[Consider] a fence or gate erected across a road] The more modern type of reformer goes gaily up to it and says, “I don't see the use of this; let us clear it away.” To which the more intelligent type of reformer will do well to answer: “If you don't see the use of it, I certainly won't let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it.”

In The Thing (1929). Excerpt in Gilbert Keith Chesterton and Alvaro De Silva (ed.), Brave New Family: G.K. Chesterton on Men and Women, Children, Sex, Divorce (1990), 53. Note: This passage may be the source which John F. Kennedy had in mind when he wrote in his personal notebook, “Don't ever take a fence down until you know the reason why it was put up.” (see John F. Kennedy quotes on this site). The words in that terse paraphrase are those of Kennedy, and are neither those of Chesterton, or, as often attributed, Robert Frost (q.v.).

[Overfishing—] it’s not just that we’re taking too many out, it’s how we’re doing it. We are wiping out their nurseries, … [because some huge boats] … bottom trawl … [with] nets that 50 years ago you’d have to lift when you came to coral reefs or rocks or nooks and crannies. Now they’re so sophisticated and so heavy, the equipment, and the boat’s so powerful they can just drag right over the coral reefs and the rocks and the nooks and crannies, and turn them into a gravel pit. … The trouble is those are the nurseries. That’s where the little fish hide and get bigger and get big enough for us to eat.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) -- Carl Sagan
